This attribute indicates the physical port number of the NAS that
is authenticating the user. It is only used in Access-Request
packets. Note that here we are using “port” in its sense of a
physical connection on the NAS, not in the sense of a TCP or
UDP port number.

Some NASes try to encode various information in the NAS-Port-Id
attribute value. For example, the MAX Ascend terminal server constructs
NAS-Port-Id by concatenating the line type (one digit), the line number
(two digits), and the channel number (two digits), thus producing
a five-digit port number. In order to normalize such encoded
port numbers we recommend using a rewrite function (see section Rewrite functions — ‘raddb/rewrite’).
A rewrite function for MAX Ascend servers is provided in the
distribution.
